BASE FOR TROLLEY-POLES.

SPECIFICATION forming* part f l'aetiel Patent N0. 659,335, dated October9, 1900.

Application filed December 26, 1899. Serial No. '741,545- (N o model.)

To all whom t may concern.-

Be it known that I, ANDREW .C .-WoLrE, a citizen of the United States ofAmerica, residing at Freeport, (Freeport post-oflice,) in the county ofArmstrong and State of Pennsylvania, have invented certain new anduseful Improvements in Bases for Trolley-Poles; and I do hereby declarethe following to bea full, clear, and exact description thereof,reference being had to the accompanying drawings, which form a part ofthis specification. I

My invention relates to an improved trolley-pole stand, the object beingto provide a means whereby the tension of the spring is I 5 releasedshould the trolley leave the line-wire,

thereby preventing the breaking ofthe trolley-poles and cross-wires; andthe invention consists of the certain details in construct-ion andcombination of parts, as will be fully described hereinafter.

In the accompanying drawings, Figure 1 is a side sectional elevation ofmy improved trolley-pole stand, which is constructed and arrangedinaccordance with myinvention. Fig. 2 is asectional plan view of the same.

To put my invention into practice and thereby provide a means wherebythe tension of the trolley-pole spring will be released should thetrolley accidentally leave the line-wire and spring upward, I provideabase-plate -1 and attach the same in position upon the top of astreet-car. Pivotally mounted upon this baseplate 1 isa rotatable frame2, in which the trolley-pole 3 is mounted upon a shaft 5 and the base ofthe said pole connected by a'strong spring b to a lever 7, suitablymounted upon a shaft or pin 8. Arranged in connection With l this lever7 is a spring-actuated keeper 1-2, pivoted to theframe 2 and used tolock the lever 7 in a vertical position, as shown at Fig. 1 of thedrawings, and the said keeper held rigid by means of a latch-lever-1`4.This.` latch-lever 14 is pivoted to the frame and is kept in' ahorizontal position by a spring-15 and small l pin 16. Attached to theouter end of the latch 4scribing witnesses.

14 is a cord 18, the other end of which is connected to thetrolley-pole3. Secured t0 the lower end of the lever 7 is a rope 9, which passesover a pulley 10 and down through an opening formed in the roof of thecar and is 5o provided with handpiece 11.

In operation should the trolley accidentally leave the line-wire thepole 3 will spring upward, and it being connected to the latch 14 willelevate the rear end, releasing its hold upon the keeper 12, therebypermitting the lever to turn about its pivotal point and occupy aposition in line with the spring 6, thereby taking the tension from thesame and allowing the pole 3 to drop beneath any of the 6o cross-wiresor to a point beneath the level of the line-wire.

To recover and bring the parts back to their normal position, it is onlynecessary to draw upon the handpiece 11 and bring the lever 7 65 backover keeper l2.

Various slight modifications or changes may `be made in the details ofconstruction without departing from the spirit of my invention.

Having thus described my invention, what 7o i I claim, and desire tosecure by Letters vPatent, is-

A trolley-pole base consisting of the pivoted frame 2, the trolley-pole3 mounted thereon, the spring 6 attached thereto, and to a le- 75 ver 7pivoted to the said frame 2, the pivoted keeper 12 and spring 13, thelatch-bar 14 and connecting-cord 18, and a means whereby the parts maybe brought back to their normal position, arranged and combined forservice, 8o substantially as and for the purpose described. i

`In testimony whereof I have hereunto affixed my signature in thepresence of two suby ANDREW c. woLFE.
